Maintenance Tips
Do not put or install the product near a heat source or under direct sunlight, or in dusty or
humid places, or somewhere the product may be hit or damaged by mechanical vibration.
To maximize the performance, it needs to be put away from equipment such as grid, large
metal objects and radar stations as far as possible.
Do not wipe the display with any chemical reagent. Solvents may damage the enclosure or
paint. If the display is stained by dust, cut off the power and then clean the display using a
dried cloth with a little of warm water. Use a clean soft cloth to clean the LED of the display.
Do not frequently switch on and off the product, which may shorten the product service life.
After the display is switched off, wait for three minutes before switching it on again. If the
product is not to be used for a long period of time, please power off the product and pull out
the power plug.
Do not maximize the brightness and contrast of the LED for a long period of time, which
may shorten the LED service life.
Do not use a hard object to write on the display, which may scratch the LED.
Clean the Infrared Tube
The interactive display uses the horizontal and vertical infrared matrix to detect and locate
the user's touch. The screen is surrounded by an infrared tube (including the infrared
acceptor and emitter), which forms an infrared net covering on the screen surface. When a
user touches the screen, fingers or other opaque objects block the infrared rays that cross
the touch point, which helps the controller detect the coordinate position of the touch point.
Dust is easily retained on the screen surface due to its long-term exposure in the air and
causes ineffective touch or inaccurate positioning. Therefore, you need to clean the infrared
tube around the screen regularly.
